sonds good,

the posting is not about XPM feature of win 7

I just installed two operating systems in my two disk partitions

Not all mathematica expressions can be convert to maple,right?

by FromMma

I've searched a translator in application center,that's for maple 9,maybe we should wait for some time?

 

> convert('Cos[\[Beta]] Sin[\[Alpha]] - Cos[\[Alpha]] Sin[\[Beta]]',FromMma)  ;
print(`output redirected...`); # input placeholder
Error, invalid minus
convertApplyFunction((Cos(Typesetting:-mambiguous(bsol(ÿ¦ÿ¢),

  Typesetting:-merror(invalid minus))) Sin(bsol(ÿ¦ÿ¡)) uminus0 Cos(bsol(ÿ¦ÿ¡)) Sin

  (bsol(ÿ¦ÿ¢)))commaFromMma)

ha,I like it,several months ago I just here more simple music in mathematica demostrations,and I love music,piano and tenor is my favourite,though I'm not such an expert at them.

I'm always dreaming a mathematical way to understand,note music and music scores,

So when we have a good command with mathematical softwares such as maple, mathematica,or matlab,then we can spend less time on other softwares such as finale (I've just installed finale 2010),sibelius and so on.

It seems the relationship between them are not so developed,

I‘d met a similiar problem something related to the page split when printing a big picture(can be converted to pdf)

Yes,When I insert a picture into the ducoment,the printed document have three pages-one blank,one picture,one blank.

When input in  math 2D type,the placeholder is in a rectangle box,I mean that,it has a name?

That can lessen pressing enter key

f:=n->(1+I)^n+(1-I)^n:
interface(rtablesize=20):
Array(1..20,f);

thanks,so is it different between writing these three commands into one box,or three?

Thanks,and the semicolon ; seems not so important? at the end of the command.

There must have somewhere that semicolon should be there.?

Actually I don't like click with mouse,and I like to input coordinates of t go chess pieces.So UI in not important for me,and for present stage the level of computer and me is not high demanding

ComplexExpand[(1 + I)^n + (1 - I)^n]=2^(1 + n/2) Cos[(n \[Pi])/4]

[1      1        1         1        1      x - I y]
             [- = -------, ------- = -------, ------- = -------]
             [z   x + I y  x + I y   x + I y  x + I y    2    2]
             [                                          x  + y ]
the expression seems interestion,hehe

 

the shourtcut keys-Ctrl+space seems no response,so how to use the fuction "Command Completion"?
